FYI, the GreenTop in Ashland, VA has plenty of powder and bullets. If you're in that area, stop in. You can also call before making that drive to see what they have in stock.
You can still edit Rifle Cartridge to include all the info for that particular group. I edit after each group as I was alternating rifles to let them cool for cold bore shots.
Even if these work out as a great load, I'll still work up another load with Varget. TAC is temp sensitive. https://ultimatereloader.com/2022/04/01/extreme-powder-temperature-testing-varget-vs-tac/
